Title: Apparatus for dispensing tickets from a stack
Inventor: KASPER KAZMIER J
IPC: G07F17/42
Filed: 1993-09-28
Abstract: An apparatus for dispensing tickets from a stack includes a base. A frame for enclosing a stack of tickets is fixedly mounted on the base. A partition wall whose position can be changed to accommodate tickets of different sizes is removably mounted in the frame. A gate for receiving tickets and allowing only one ticket at a time to pass through is also fixedly mounted on the base. The gate includes a slider element which is adjusted to different heights by a screw having two different sized threads in order to accommodate tickets of different thickness. A toothed blade is disposed underneath the frame and a mechanism which includes a motor driven rack and pinion is coupled to the toothed blade for bringing the toothed blade into engagement with the lowermost ticket in the stack, moving said toothed blade so that the lowermost ticket is transported from the stack into the gate, bringing the toothed blade out of engagement with the ticket and then moving the toothed blade back to engage the next ticket in the stack. A removably weight is seated on top of the stack to push the stack down against the toothed blade. A ticket holder is provided to assist in loading tickets into the frame.

Title: Method and device for electrostatically investigating surface and sub-surface structures
Inventor: FORTIN GABRIEL
IPC: G01V3/08
Filed: 1991-08-01
Abstract: An electrostatic sensing device for investigating a surface and/or sub-surface structure comprises a central and square electrically conductive sensor plate, and four side electrically conductive elongated and rectangular sensor plates connected together and each disposed adjacent and parallel to one edge of the central plae. The arrangement of sensor plates is applied to the surface, and the central and side plates are then electrically charged at different rates, the charging rate of the central plate being affected by the permittivity of the investigated structure to electric field. A differential amplifier (49) amplifies the difference between the voltages on the central and side plates as these plates charge, and a peak detector (61) detects the highest amplitude of this amplified voltage difference and displays it on a voltmeter (4). As the permittivity of the structure under investigation is function of at least one characteristic thereof, and as the voltage difference is affected by the charging rates of the central and side plates themselves affected by the permittivity to electric field, the output signal from the peak detector (61) is indicative of this characteristic of the inspected structure.

Title: Manufacture of trimethylolpropane
Inventor: SALEK JEFFREY S
IPC: C07C29/38
Filed: 1993-08-27
Abstract: Trimethylolpropane of high purity is efficiently made by mixing the aldol reaction product of formaldehyde and n-butyraldehyde with at least about 20 wt % of a lower alcohol prior to hydrogenation to allow recovery of high purity product by simple distillation. In a less preferred mode, the alcohol may be added after hydrogenation, resulting in a smaller improvement over previous processes.

Patent CA-2137771-A1 (CA)
Title: Method and apparatus for refrigerant reclamation
Inventor: ZUGIBE KEVIN J
IPC: F25B45/00
Filed: 1994-12-08
Abstract: The  apparatus  for  reclaiming  refrigerant includes a bypass line (30) for hot gas coupled to a distillation  liquid  temperature  control  (26),  which controls the temperature of the system to remain at a very  low  temperature  setting  in  order  to  prevent moisture carry-over, and maintain an exact liquid level. The distillation chamber  (16)  itself contains a heat exchange system and comprises an outlet subsystem (50) for distilled refrigerant, as well as an inlet (12) for contaminated refrigerant. Vapor forms above the liquid in  the  chamber  (16)  which  is  discharged  into  a compressor (36),  which feeds back hot gases through a helical   coil   arrangement   (22)   immersed  in   the distillation   chamber   (16).   The   compressor   (36) alternatively bypasses the helical coil (22) under the control of the temperature controller (26).  In either event, either from the bypass or from the coil a small air  cooled  condenser  (46)  dissipates  heat  from  the compressor work. The system is thus devoid of the usual air  or  water  cooled  condensers  to  condense  the refrigerant and/or external electrical heaters.

Title: Hollow polymer latex particles
Inventor: LEE DOLK
IPC: C08F285/00
Filed: 1992-08-19
Abstract: This invention relates to polymer particles that are acid-free in the swellable polymer core and to hollow polymer particles derived therefrom, and to a process for the production of these particles. The acid-free core advantageously decreases the polym-er particle's affinity to water. Applicants have discovered that non-carboxylated latexes having a variety of T g's will swell at tem-peratures higher than the T g of the polymer. These latex particles are useful as opacifying plastic pigments for various coat-ings and particularly as gloss-enhancing plastic pigments for paper and paperboard coatings. Preparation of the hollow polymer particle comprises the use of (meth)acrylate ester monomers, vinyl esters of carboxylic acids or a mixture thereof which are hydrolyzable and swellable at higher temperatures in alkaline environments. The particles may be encapsulated with a hard shell.

Title: Fuel cell and method for moistening the electrolyte
Inventor: STRASSER KARL
IPC: H01M8/04291
Filed: 1992-08-10
Abstract: Abstract In the case of fuel cells having an electrolyte which conducts oxygen ions,, hydroxide ions or protons, the problem fundamentally exists of moistening the air of the combustion gases in order to prevent the electrolyte drying out or thinning and thus to prevent defective operation of the fuel cell during air operation. In this case, the design and financial cost, in particular, for moistening of the air is of concern.        In  order  to  avoid  this  disadvantage,  it  is provided according to the invention that exhaust gas, which occurs on the cathode side, of the fuel cell is at least partially recirculated into the cathode of the fuel cell. In consequence, the water content of the electro-lyte can be set within wide limits by simple adjustment of the recirculated exhaust-gas quantity. In consequence, economical use of the PEM fuel cell becomes possible.        The invention can be used in principle for all fuel cells having an electrolyte which conducts oxygen ions, hydroxide ions or protons.

Title: Metal mould for making a frozen confectionery product and a method for making the mould
Inventor: GRAM KLAUS
IPC: A23G9/22
Filed: 1994-03-02
Abstract: A metal mould for making a frozen confectionery product may be manufactured from titanium materials. The mould is produced by cold-working a sheet-formed blank, either by deep-drawing or by pressing two half shells which are subsequently welded together. When using titanium for the ice lolly moulds, it is possible to avoid the use of poisonous inhibitors, without any risk of corrosion on the moulds. There is a considerable risk of corrosion on the moulds as the moulds used in the production of frozen confectionary products are subjected to freezing baths with strong saline solutions. When using titanium material for making the metal moulds, it is further possible to perform stress-relieving annealing at a lower temperature than was formerly possible when the moulds were made from stainless steel.

Title: Radar apparatus
Inventor: VAN GENDEREN PIETER
IPC: G01S13/24
Filed: 1995-10-20
Abstract: The invention relates to a radar apparatus (1, 2, 3) provided with a doppler filterbank (4) and fast thresholds (5.i), for writing per pulse a range-doppler matrix in range-doppler memory (6) and the background level in background memory (7). By unfolding the range-doppler matrices and combining the unfolded range-doppler matrices for all the pulses in a burst in combination means (10), an incoherent combination of the pulses is obtained before an actual detection takes place. This cluster before detect scheme increases the detection probability for weak echoes, without increasing the false alarm rate.
